Patented Sept. 16, 1930 Param `Fries BERT MCBRIDE, OF ADA, OHIO SHOCK BINDER Application filed September 12, 1527. Serial No. 219,159.

This invention relates to the art of bind` ing sheaves' ofgrain, fodder and analogous farm products', into bundles or shocks, and more particularly to a device which is adapt- V ed Vfor binding orV compressing sheaves of grain or the like, by means of a flexible binding element operatively associated therewith.

, The invention has for its principal purpose, the provision of a binding device hav- Y ing a mechanism which is actuable in a'manf ner similar to manually drawing the end portions of a iiexibleielement such as a sash cord taut, after the major portion thereof has beenplaced about asheaf or shock of grain subsequent to the binding thereof.

v To accomplish this action, the present invention embodies a pair of toothed racks which are carried by and operatively dieposed through a suitable housing or casing, ZOan'd are formed to substantially follow the contour of a sheaf or shock of grain upon the binding thereof, in conjunction with a pinion housed within theY casing and manually rotatable to move the racks in opposite '25 directions, through the instrumentality of a pivoted shaft and crank handle formed therewith. Thefdiagonally extended opposite ends of the racks have a stout cord connected thereto for passage around a sheaf or shockv of grain to compress the same. Qbviously, when a sheaf or shock has been suitably compressed, it may be readily and finally secured with suitable cord or a like agency for the purpose.

Another purpose is to provide a housing or casing in conjunction with a plurality of rollers which are positioned adjacent Vthereto, for guiding the protruding diagonally disposed racks, so that-they may operate free- '40 ly without binding the actuating pinion and whereby/the outer ,free end'thereof may be .'directedvaway from the shock or sheaf, when the racks are operated'to draw the cord binding element tautk abouta shock or sheaf of grain.

A further purpose is to provide a novel VVlocking means na-dapted'to engage the teeth ofone of the racks in conjunction with the sidel of the casing, to hold the racks and w pinion therefor, against areverse or releas- )movement thereby.

ing movement, after a sheaf or shock has been compressed thereby, so that the operator may be free to bind the same with suitable cord means in the well known manner.

A still further purpose of the invention, is the provision of a twine or cord holding and cutting means, which is attached to and adjacent the 'tree end of one of said racks, to eliminate the requirement fora pocket knife or the like, for cutting the binding cord supply from the portion secured about the shock. n temporary ycord securing means is further provided on the opposite end ofthe other of said racks, so that the binding element or cord may be securely connected to the rack during the compressing operation'and at the saine time readily removable from the securinglmeans after the shock has been ultimately tiet.

The invention comprises further features,

arrangements, and combination of parts hereinafter set forth, illustrated in the accompanying sheet of drawing and defined in the appended claims.`

In the drawing: u Fig. l, is a perspective view illustrating the manner of applying the shock binder to a sheaf of grain, and wherein the same ,is `fully compressed and with' the binding Vmechanism shown fully actuated and locked against retrograde movement. v l

Fig. 2, is a top plan view of the shock binder as `applied to a loose formation of grain stalks, and illustrating the position of the binding mechanism prior to a binding Fig. 3, is a vertical section through the housing illustrating the manner of positioning the racks, rollers and pinion therein. y

Fig. 4, is an enlarged perspective viewof the temporary binding element anchoring means carried by one of the racks adjacent one end thereof. Y

Fig. 5, is a transverse sectional view through the casing, illustrating the diagonally and oppositiely disposed rack openings and relative position of the'rollers thereto.V

Referring to the drawing in detail, l identilies a metal housing or casing which may be of any suitable size and conguration. The

31, which is attached to one of the bolts 8, supporting the rollers 9. A l y The invention having beenset forth, what I claim and desire to secure by Letters Pat= tent is: 4

1. In a shock hinder, the combination with a pair ot racks adapted for opposite directional movement, of a flexible binding element operatively associated with said racks for binding a shock of grain, a housing vfor movably supporting said racks, unitary manually operable means carried by said hous- Ving for actuating the racks and binding ele- "flexible binding element operatively associated with said racks for compressing a shock of grain, a housing for movably supportingsaid racks, unitary manual-ly operable means carried by said housing for actuating the racks and binding element simultaneously, rack guiding means formed with said housing, and rotatable means co-acting with said last named means for maintaining said racks in diagonal paths of travel.

Y 3. A shock binder comprising a casing having a plurality of diagonally opposite openings therein, a pair of arcuate racks having' their teeth formedl at acute angles with respect to thel curvature of said racks movably supported in said casing in spaced relation, a pinion journaled in said housing between said racks for operative engagement therewith, manually operable means connected with said pinion outwardly of said v casing for actuating said racks and pinion, a

VMk

plurality of rollers journalled in said casing adjacent said openings for maintaining said rac-ks in constant Contact with said pinion throughout their lopposite paths of travel, means provided at certain ends of said racks Jfor g attaching a flexible' binding element thereto, locking means carried b-y said casing for straddling one toothed face of said racks at a point adjacent said casing to prevent retrograde movement of said racks and pinion, and a cord cutting and supporting means secured to one of said racks adjacent the binding element connecting end thereof f as and for the purpose set forth.

In testimony whereof I atEX my signature. Y
